| Ash trees in the American midwest are rapidly falling victim to the emerald ash borer beetle invasion, first detected in the early 1990s. Millions of trees have been destroyed in the Chicago suburbs and other widespread locations in an effort to stem the tide. However, the beetle is spreading and it appears little can be done to prevent it from broadening its range. I lost the single biggest plant on my property in 2007, a huge ash tree that shaded the front of my house. I wish the developers had known then what we know now and planted a hardier variety of tree. |
 This 57-year-old Korean ash at the Morton Arboretum has so far escaped damage by EAB. |
